SUMMARY OF THE INVENTION This invention relates generally to roof edgestructures and more particularly to a combination water dam, sealerstrip and fascia structure which functions as an edge structure for aflat roof deck.

Roof edge structures are well known in the art. An example of a priorart roof edge structure is one which comprises a combination water dam,sealer strip and fascia structure, and wherein the sealer strip isrockably mounted on the rooting material to provide an upward thrustagainst the upper end of the fascia member for securing the fasciamember in place. A disadvantage of the lastmentioned prior art roof edgestructure, and similar devices, is that the sealer member is pivotallymounted on the roofing material on the upper end of the water dam orcant, and the thickness of the roong material on a single roof varies sothat it is not possible to provide a positive and accurate pivot pointfor the sealer strip. A further disadvantage of the aforementioned priorart roof edge structures is that they provide only a single line ofsealing between the roong material and the Water darn or cant and theroong material must be trimmed flush with the upper pivot end of thecant. A still further disadvantage of the aforementioned prior art roofedge structure is that due to the pivot arrangement of the sealer stripit is diflicult at times to mount the fascia member in position becauseof the overly thick roong material Ff"ce on which the sealer strip ispivoted to provide the required upward thrust for securing the fasciamember in position. Accordingly, in view of the foregoing, it is animportant object of the present invention to provide an improvedcombination water darn, sealer strip and fascia structure fora roof edgestructure which overcomes the aforementioned disadvantages of the priorart roof edge structures. i

It is another object of the present invention to provide a combinationwater dam, sealer strip and fascia structure which is constructed andarranged so that the sealer strip pivots about the upper end of thedarn, in direct contact therewith, and the sealer strip also engagesagainst the rear face of the fascia member andy moves the fascia memberinto a secured position with a downwardly and inwardly directed forceagainst the upper end of the fascia member.

It'is still another object of the present invention to provide acombination water dam, sealer strip and fascia structure which ismounted around the edge of a roof edge, with the roong material pliesextended over the water dam or the cant, but wherein the rootingmaterial plies do not extend to the upper end of the water dam or cant.

It is a further object of the present invention to provide a combinationwater dam, sealer strip and fascia structure for a roof edge and whereinthe sealer strip moves the fascia member into a xed position with aforce exerted against the upper end of the fascia member that acts in adownward and inward direction, so as to move the fascia memberdownwardly and the upper end of the fascia member inwardly and the lowerend of the fascia member outwardly.

It is still a further object of the present invention to provide acombination water dam, sealer strip and fascia structure for a roof edgewherein the sealer strip is adapted to form a plurality of compressionseals on the roofing material.

It is still another object of the present invention to provide an edgestructure for a flat roof having a built-up roofing covering including aplurality of roofing plies, and such structure comprises a cant havingan outer vertical portion extending above the roof and secured to theouter edge of the roof, and having an inner portion inclined inwardlyand downwardly to the roof and secured to the roof, with said roofingplies laid over said inner inclined portion; the upper end of the cantouter vertical portion being integrally joined to the upper end of theinner inclined portion; a fascia member having the lower end releasablyengaged with the lower end of the cant outer vertical portion, andhaving the upper edge thereof folded inwardly, and downwardly andoutwardly, to form a hook with an upwardly facing support lip; a sealerstrip having a downwardly facing hook formed along the upper edgethereof and extended into the hook formed along the upper edge of thefascia member, and with the edge of the sealer strip hook engaging theupwardly facing support lip of the fascia member hook; said sealer striphaving its upper end in`=pivotal engagement with the upper end of thecant vertical portion and the body portion thereof pivoted downward intosealing engagement with said rooting covering so as to move the fasciamember downwardly and the upper end of the fascia member inwardly, andthe lower end of the fascia member outwardly into a retaining engagementwith the lower end of the cant vertical portion; and means for securingthe sealer strip to said cant inner inclined portion and to compress therooting covering against the cant inner inclined portion to form aweather seal.

Other objects, features and advantages of this invention will beapparent from the following detailed description, appended claims, andthe accompanying drawing.

BRIEF DESCRIPTION OF THE FIGURES IN THE DRAWINGS FIG. 1 is afragmentary, vertical section view, in perspective of an illustrativeembodiment of the present invention; and

FIG. 2 is a slightly reduced, elevational section View of the embodimentof FIG. 1, taken along the line 2--2 thereof, and looking in thedirection of the arrows.

PARTICULAR DESCRIPTION OF THE INVENTION Referring now to the drawing,and in particular to FIG. 2, the numeral designates a vertical wallmember which is connected to the lower side of a conventional base roofdeck 2 x 4 portion 11. The numeral 12 designates the roof insulationportion of the roof deck. The combination water dam, sealer strip andfascia edge structure of the present invention functions as an edgestructure for a flat roof deck, as illustrated in FIGS. 1 and 2.

As shown in FIGS. 1 and 2, the combination water darn, sealer strip andfascia structure of the present invention broadly includes a metal waterdam or cant generally indicated by the numeral 13, a metal fasciagenerally indicated by the numeral 24, and a metal sealer stripgenerally indicated by the numeral 31.

The water dam or cant 13 may be made to any desired length and from anysuitable material, as for example, galvanized sheet metal. The watercant 13 comprises an outer vertical portion or leg 14 which is securedto the outer side of the roofing deck 2 x 4, 11, by any suitable means,as by a plurality of l" long galvanized roofing nails 15. The nailsv 15may be employed at any desired center spacings, as for example at 24center spacings. The water cant 13 further includes the integral,downwardly and outwardly inclined, or sloping, flange 1,6 on

the lower end of the vertical leg 14. The flange 16 functions as a dripedge.

It will be seen that the water cant vertical leg 14 extends above therooiing deck 2 X 4, 11, for a predetermined distance, as for example, 3"or 4", as desired. The water cant vertical portion 14 terminates at itsupper end in an integral, downwardly facing U-shaped channel 17. Thewater cant 13 further includes an inwardly and downwardly inclined innerportion which comprises a first inclined leg portion 18 which isintegrally connected to the inner iiange of the downwardly 'facingchannel 17, and a second inclined leg portion 19 integral ly connectedto the leg portion 18. The first inclined leg portion 18 inclinesinwardly and downwardly at a rst acute angle relative to the verticalleg 14. The second inclined leg portion 19 of the inclined leg of thewater cant 13 inclines inwardly and downwardly from the lower end of theiirst inclined leg portion 18 at a second acute angle which is a greaterangle than said iirst acute angle. As illustrated in FIG. 2, theaforementioned first acute angle between the first inclined leg portion18 and the vertical leg 14 is approximately 10. The aforementionedsecond acute angle between the second inclined leg portion 19 and thevertical leg 14 is approximately 45.

Integrally formed on the lower end of the second inclined leg portion 19is a horizontal ange or extension 20 which is adapted to be secured tothe roong deck 2 x 4, 11 by any suitable means as by a plurality of 1"galvanized rooting nails 21 which are disposed at predetermined centerto center distances, as for example l2. The flange 20 is integrallyconnected to the lower end of the second inclined leg portion 19. Theange 20 is bent upwardly through an acute angle from the plane of theinclined leg portion 19 and is disposed substantially perpendicular tothe outer vertical leg 14.

The numeral 22 designates each of the various roofing plies which formthe built-up roong covering. The roofing plies 22 are overlaid in theusual manner by a layer of gravel bitumen 23. As shown in FIG. 2, theplies or layers of roofing material 22 are laid over the water cantflange 20, and they extend upwardly toward the edge of the roof, overthe cant inclined leg portion 19, and into engagement with the cantinclined leg portion 18. It will be seen that the outer edges of thelayers or plies of roofing material 22 do not extend to the upper end ofthe cant inclined leg portion 18 and that they do not have to be trimmedoff iiush with the end of the inclined portion 18.

The numeral 24 generally designates an elongated external metal fasciawhich may be made from any suitable metal, as for example extrudedaluminum. The fascia 24 comp-rises the vertical body portion which is inthe form of a vertical plate. The lower edge of the fascia body por tionis bent downwardly and outwardly to provide the inclined ange 26, at thelower outer end of which is integrally formed the folded-over orU-shaped portion 27 and the integral iiange 28 which slopes upwardly andinwardly. The flanges 26 and 28 and the U-shaped portion 27 comprises adrip hook configuration or channel which is adapted to receive andengage the drip flange 16 on the lower edge of the cant outer leg 14, asexplained more fully hereinafter.

As best seen in FIG. 2, the upper end of the fascia body portion 25 isrolled or folded over inwardly as indicated by the numeral 29. Theextreme upper edge of the fascia body portion 25 is further turneddownwardly and then outwardly toward the fascia body 25 to provide ahook coniiguration which faces outwardly and which includes a supportlip 30 that extends outwardly under the rolled over portion 29.

The sealer strip is generally indicated by the numeral 31, and it may beformed from any suitable material as, for example, extruded aluminum.The sealer strip 31 includes the upper body portion 32 which isintegrally connected at its upper end with the flange 33. The flange 33is disposed at an obtuse angle relative to the upper surface of thesealer strip upper body portion 32. The upper edge of the flange 33 isfolded over inwardly and then downwardly to form a downwardly facinghook or U-shaped channel. As shown in FIG. 2, the hook on the upper endof the flange 33 is adapted to be received within the hook formed on theupper end of the fascia member 24. The lower edge of the outer arm 35 ofthe lastmentioned hook is adapted to engage the upwardly facing lip 30on the hook on the upper end of the fascia member 24. The lower bodyportion of the sealer Strip 31 is designated by the numeral 37. Thesealer strip upper -body portion 33 is joined to the lower body portion37 by a longitudinally extended indentation which provides a firstsealing ridge 36 for sealing engagement with the roofing material plies22. A second longitudinally extended indentation is formed along thelower end of the sealer strip lower body portion 37 to provide a secondsealing ridge 38. The numeral 39 designates the up-turned lower edge ofthe sealer strip 31.

The seaer strip 31 is provided with a plurality of longitudinally spacedapart, prepunched holes 40 for the reception of sealing grommets 41 andl stainless steel slotted, hex washer head screws 42. The grommets 41may be made from any suitable material as, for example, neoprene.

In use, the roof edge structure of the present invention is mounted on aroof stiucture by first installing the water dam or cant 13. The cant 13is nailed by means of the nails 15 to the edge or side of the roof. Thecant flange 20 is then nailed by a plurality of nails 21 to the top ofthe roof structure. The building material plies 22` are then overlaidover the cant inclined leg portions 18 and 19. As shown in FIG. 2, theplies 22 do not extend to the upper end of the inclined leg portion 18.The fascia member 24 is next mounted in place with the inwardly andupwardly directed fiange on the lower end thereof in engagement with thefiange 16 on the lower end of the cant body portion 14. The sealer strip31 is then mounted in the dotted line position 43, shown in FIG. 1, withthe hook on the upper end thereof inside the hook on the upper end ofthe fascia member. Sealer strip 31 is rotated downwardly to thefull-line position shown in FIG. 2, so that the sealer strip is pivotedaround the upper end 17 of the cant body portion 14. Simultaneously, thelower end of the sealer strip flange 33 engages the inner face of thefascia member body portion at the joint edge or pivot edge 45, as shownin FIG. 2, and continued downward movement of the sealer strip 31 movesthe fascia member 24 downwardly, and the upper end thereof inwardly, andthe lower end thereof outwardly so as to bring the flange 28 of the hookon the lower end of the fascia member 24 into engagement with the rearside of the flange 16 on the lower end of the cant body 14. The sealerstrip 31 is attached to the cant inclined leg portion 19 by a pluralityof sealer grommets 41 and the sealer screws 42. A nail is thrust throughthe prepunched holes 40, which are used as guides for the nail, and thenail is used to punch a hole 44 through the cant inclined leg portion19. The screws 42 are threadably secured in place in the holes 40 and 44by any suitable means as, for example, by a hand screwdriver or apower-operated torque wrench. It will be understood that the sealergrommets 41 would be squeezed into the holes 40 in the sealer strip 31to seal the roofing material about these holes. It will also beunderstood that the two sealing ridges 36 and 38 provide a sealingbarrier against snow or water which may be forced by winds up theinclined surface of the roofing material on the cant leg 19.

The fascia members 24 may be made in any length as, for example, inlengths. The adjacent ends of the fascia members 24 may overlap eachother or they may be connected by suitable splice plates as indicated bythe numeral 46 in FIG. l. The fascia members 24 are free to expand andcontract longitudinally, and they are free to slide relative to oneanother over the splice plates 46, or over the overlapped ends if theoverlapping structure is employed. The splice plates 46 may be providedwith a configuration consistent with the configuration of the roofingedge as, for example, at a corner of a roof structure the splice plate46 may be angularly formed.

While it will be apparent that the preferred embodiment of the inventionherein disclosed is well calculated to fulfill the objects above stated,it will be appreciated that the invention is susceptible tomodification, variation and change.
